To all whom it may concern:

Be it known that l, UnAnLEs h. Mclan LANDJL citizen of the UnitedStates, rsidin at Kingston, in the county oi Luzerno and State ofPennsylvania, have invented certain new and useful improvements inAdding-Machines, of which the following is a specification.

The chief object of the present invention is to provide adding machinesand the like with an attachment which will serve the pur iosc ofcounting the number of operations oi the machine in accumulating items,as for example in listing bank checks and accunnilating the totalthereof. The invention aims lo provide an item counter for machines ofthis character which will have suflicicnt capacity serve for anyreasonable length of the listmg operations and can be readily reset to.aero for a new series of operations. it should be understood at theoutset that the purpose is not to register every operation of themachine, as for example every vibration of the o crating handle in handoperated niac- 'nes, because this would not subservc a articularlyuseful purpose, inasmuch as lank or s acing strokes are frequently takenin the or 'nar use of machines of tlus character and furtl ermore totalprinting requires separate operations of the machine and there would beno special object in keeping count of the number of times the in achifiemight be operated to take a total. The present inventron does not,therefore, provide simply for the a plication of a counting orregistering att-ac iment to adding machines for the pur pose of showinghow many times the machine may have been operated, but entailsinstruinentalitics whereby an accurate account may be kept of thoseoperations of the machine which record or register the separate itemswhose sum is to be obtained through the operations of theaccumulatingmechanism of the machine. Thus, the invention providesautomatic means for showing, the total number of checks for examplewhich have been listed in arriving at the'statc of a depositors accountiri'abank. This is re-\ ferred to merely as one example of the uses towhich such an attachmentmay be put and it will be obvious that it can beadvantageously emplo ed in connection with many other uses to w rich thecommercial adding machine olthe present day is put.

illustra to W'ith the above stated and incidental ob jrcts in View, theinvention consists in certain novel feai u of construrtio i and com--binations of parts, the csscniin elements Whcrcof arc recited in theappended claims and a preferred. form of embodiment of which isdescribed in detail hereinafter and fully illustrated in thc accom'ianying drawings forming part of this specification.

()i said drawings, Figure 1 represents, partly in longitudinalsectionand )artly in side elevation, a sufficient portion oi anaddingland listing: machine to show the manner of coopm'ation therewithof the present invention; and Fig. 2 re resents the same machine in planview wit a portion of the keyboard broken away.

In the resent instance, the invention is d and describcdfas applied tothat type of adding and listin mac unc known as t e Burroughs and'gyp'ed;for example in Letters Patent No. 04,963, issued September 12, 1893.This t pe of adding machine is well known, bein disclosed in a number ofprior atents in ad ition to the one just men tioned and also beingextensiyel r employed inbanks and commercial establis merits. it willnot, therefore, require detailed description and the presentspecification will sirn p y refer to those parts of a Burroughs addingma chine with which the present invention is more or less closelyassociated. In machines of this type, amount keys 291 are arranged in anumber of parallel rows or series, the keys of each row bein numberedfrom 1 to 9 and in an operation or adding and printing an item the keysrepresenting the amount depressed and then a driving shaft is opcratedeither b hand or by power to cause the addition of t c amount and thelisting of the same. The keys 291 act through levers 217 to set stopsforcontrolling the extent of movement of the recording and registering oraccumulating devices and a set of these levers 217 below any row of keysoperate in slots of a slidin strip or plate 214 which in connection witthe latch 228 constitutes means in the-nature oira detent to hold thekey of that row depressed during so much of the operation of the machineas must be controlled by the-stop, set by the key. The strips 214 areformed with de ending lips or lugs 214 which overlie the ront side of auniversal cross rod 402 forming part of the bail comprising in additionto said rod side arms 424, one of which appears in Fig. 1. Spiralsprings 402*, one of which appears in Big. I, serve to draw said bailforward, the latter being pivotally mounted at its lower end u on across shaft or rod 409. it will be seen, lowever, that upon depressingany one of the keys 291 in any .ne of the rows or series this bail willhe drawn-rcarwardly by reason of the action of one of the lips 214,against the universal rod 492. This bail has been heretofore employedinmachines of this character, but its previous functions need ,not behere described. For the purposcsof the present invention, the customaryiovements of the bail are availed of to estab ish an operativeconnection between the operating mechanism of the machine and the itemcounter which is preferably attached to the casing of the machine at theupper left hand part thereof, as shown in Fig. 2, where the count can beeasily read through the casing 1690 of the item counter. The interiormechanism of the latter may be ofany well known character, whereby, fore ample, the oscillations of a driving shaft otruding from said casingwill cause step step ad'vanceof one numeral wheel or sk and eachcomplete revolution thereof will be carried to the adjacent numeral diskand so on through as man disks as desired. In he present instance, t eitem counter is Bho 'n as equipped with four numeral disks 1639 so as toafford a capacity of 9,999 counts. The reference numeral 1633designatesa knob or handle by which the said nunieral disks or wheels may beturned to zero in any well known manner which requires no detaileddescription, and the reference numeral 1601 do nates the oscillatorydriving shaft which prb e cts through the casing 1690 and in the presentinstance through a bushing 1631 occupyin a boss 1629 on the casing ofthe machine, t e item counter being secured in place on the'la-tter bymeans of a knurled collar 1636 screws-(f upon said bushin and againstsaid boss.

he driving shaft 1601 has secured to it a crank arm 1611 witharoll-bearing Wrist pin 1612 projecting laterally therefrom, as shown inFig. 2. On the opposite side of said crank arm there is a laterallyprojecting stud 1653, to'which is attached one end of a spiral sprin1685, the opposite end of which is secure to a stationar support in thecasing of the machine, sai spring serving to -normally draw the crankarm rearwardly. For ward movement of said crank arm causes advance ofthe rimary wheel of the item counter in a well known manner, and thesubsequent retraction of said crank arm by the spring repares thecounter for the next advance of said primary wheel. The forward movementof the crank" arm is effected in the present instance through theinstru- 'drawn forward hy its springs 402.

the link 1619 is again depressedand the op- 130 mentality of a link 1619which, at its rear end takes the form of a hook designed to engage therear side of the wrist pin 1612. At its forward end this link ispivotally connected with an upward extensionof one side plate or arm 613of the usual restorin frame of a Burroughs adding machine. T is frame iscustomarily mounted to rock or swin upon a shaft 609 and in each 0eration of t e machine oes through a regu ar and uniform eX- tent ofoscillation through appropriate connection with the shaft 300 of theadding machine, to which shaft the driving power is applied. It will notbe necessary to enter into the details of this operation. Sufiice it soto say that the regular and uniform oscillation of this restoring frameis availed of to produce oscillation of the crank arm 1611 of the itemcounter, through the medium of the link 1619, which, however, is notnoras mally in position for engagement with, said crank arm. ltsengagement therewith-sis controlled from the amount he s 291, sh hatonly when one. or more of said keys has l eon depressed, will thereexist an operative relation between the item counter and the operatingmechanism of the machine, hence only when the machine is registering orrecording an item will count be made of the operation. 1 The manner inwhichthc operative conneetion between the operating mechanism of themachine (1 of the item counter is controlled from the keys is asfollows: The bail, composed of the universal rod 402 and the side plates424 has one of its side plates connected b a link 1620 with'one arm of ahell crank liiver 1621 mounted upon the cross shaft or rod 602, theother arm of said bell crank lever carrying a roIler-equi pad pin orstud 1622 engagin a lo 'tudinal slot 1623 in the link 1619. lhe 1620 is,of course, ivotally connected with the bail and the bell crank lever andwhen said bail is moved rearwardly by the depression of an amount keythe bell crank le'ver will be c0rrespondingly rocked rearwardly throughthe medium of said link and thereby the link 1619 will be elevated by meonof the on" gagement of the roller-oquifi ped pin- 1622 with the up orside of the 5 0t 1623 This will have t e effect of locating thehookshaped rear end of the book 1619 behindflthe wrist pin 1612 of theitem counter crank 1611. It results that when the machine is '120operated and the restoring frame 618 swung rearwardly the link 1619 willbe drawn forwardly and with it the said crank arm, whereby a count ismade of the operation.

At the conclusion of the machine a opera- 126 tion, the latch 228 isdisplaced in the usual manner and the strip or plate 214 slid to its wnormal position the bail 402- 424 being Thus,

erative connection broken between the opism, an item counter normallydisconnected therefrom, and amount kcysl'or establishing cratingmechanism'of the machine and the item counter.

It will be seen that the construction above described provides forcounting up the number of operations of the machine in UCCLUHU- latingor recording items and that no other operations of the machine ailectthe item counter and thus the objects primarily stated are accomolished.It will, however, be understood that the form. of embodiment here indisclosed is susceptible of considerable modification and that theinvention is by no means confined to this particular construe tion.Hence in claims which follow, the essential elements of the inventionare recited without limitation to details.
